Potential Risks to the Environment as a Result of Pesticide Handling in the Nanumba-North Municipality, Ghana

The present study deduced the potential risks to the environment as a result of pesticide handling in the Nanumba-North Municipality of the Northern Region of Ghana. Cluster sampling was used to select 30 communities from Nanumba-North Municipality. Simple random sampling and purposive sampling were used respectively to select 7 households from each community and one farmer from each household, giving a sample size of 210 farmers. The instrument used for the study was a questionnaire of respondents. The quantitative data obtained were analyzed using frequencies and percentages. The study concluded that 11 types of pesticides are commonly used by the farmers on their fields, with atrazine (22%) being the most commonly used pesticide which is an herbicide, and deltamethrin (1%) was the least used pesticide which is an insecticide. The study, therefore, recommends that appropriate authorities in the area should inculcate means to enlighten farmers on the best way of pesticide utilization that can beef up the ambition of sustainable agricultural production and desirable environmental conditions.

Development of a Web-Based GIS of Flood Zones in the Municipality of Ouagadougou in Burkina Faso

This document describes the creation of an informative Web GIS aimed at mitigating the impacts of flooding in the municipality of Ouagadougou, in Burkina Faso, a region that is highly sensitive to climate change. Burkina Faso, which is undergoing rapid urbanization, faces major natural threats, particularly flooding, as demonstrated by the severe floods of 2009 that caused loss of life, injury, structural damage and economic losses in Ouagadougou. The aim of this research is to develop a web map highlighting the municipality’s flood-prone areas, with a view to informing and raising awareness of flood risk reduction. Using the Leaflet JavaScript mapping library, the study uses HTML, CSS and JavaScript to implement web mapping technology. Data on Ouagadougou’s flood zones is generated by a multi-criteria analysis combining Saaty’s AHP method and GIS in QGIS, integrating seven (7) parameters including hydrography, altitude, slope, rainfall, soil types, land use and soil moisture index. QGIS processes and maps the themes, PostgreSQL with PostGIS serves as the DBMS and GeoServer functions as the map server. The Web GIS platform allows users to visualize the different flood risks, from very low to very high, or the high-risk areas specific to Ouagadougou. The AHP calculations classify the municipality into five flood vulnerability zones: very low (24.48%), low (27.93%), medium (23.01%), high (17.11%) and very high (7.47%). Effective risk management requires communication and awareness-raising. This online mapping application serves as a tool for communication, management and flood prevention in Ouagadougou, helping to mitigate flood-related natural disasters.

Application of Information Technology in Institutions and Challenges of Human Resources-Case Study: Administration of the Municipality of Ferizaj

This study aims to investigate how information technology is applied in the administration of the municipality of Ferizaj and what are the challenges with human resources, the work was carried out through a case study in the municipality. This paper highlights that the use of information technology provides higher efficiency for the performance of daily work in the municipality, thus also the provision of better services to citizens. However, the level of use of information technology in the Municipality of Ferizaj leaves much to be desired in terms of efficiency because a significant number of employees have not attended adequate training for the effective and efficient use of various IT applications and have not are still adapted to the digital environment in the municipality. Therefore, the recommendation derived from this paper is that the information technology environment in the municipality of Ferizaj needs to be improved by providing staff with adequate qualifications, while for those who are currently engaged in the municipality and who do not have adequate qualifications, training should be provided in a way that all users of IT applications are fully integrated into the digitized environment in order to be effective and efficient in providing services to citizens. This simultaneously gives the municipal staff job security and motivation for better services for citizens. Also, information technology enables a better control over the activity of the municipality because every action is recorded as data which can then be used to analyze the performance of the municipality.

Upcycling municipal solid waste to sustainable hydrogen via two-stage gasification-reforming

As global municipal solid waste(MSW)quantities continue to escalate,serious socio-environmental challenges arise,necessitating innovative solutions.Waste-to-hydrogen(WTH)via two-stage gasification-reforming(TSGR)presents an emergent technology for MSW upcycling,offering to ease waste management burdens and bolster the burgeoning hydrogen economy.Despite early initiatives to advance TSGR technology,a cohesive and critical analysis of cutting-edge knowledge and strategies to enhance hydrogen production remains lacking.This review aggregates literature on MSW upcycling to hydrogen via TSGR,with a focus on optimizing process control and catalytic efficiency.It underscores technological avenues to augment hydrogen output,curtail catalyst costs,and refine system performance.Particularly,the review illuminates the potential for integrating chemical and calcium looping into TSGR processes,identifying opportunities,and pinpointing challenges.The review concludes with a summary of the current state of techno-economic analysis for this technology,presenting outstanding challenges and future research directions,with the ultimate goal of transitioning WTH from theoretical to practical application.

Microstructural analysis of marl stabilized with municipal solid waste and nano-MgO

Municipal solid waste(MSW)is accumulating over elapsed time across the world,and it is observed in many projects associated with weak soils,such as marl.Therefore,effective solutions to the environmental problem are essential.Conventional techniques for stabilizing marl generally use substances such as lime and cement,which could exacerbate pollution.For this,some new stabilizers,e.g.nano-MgO,are used.There are large quantities of marls and MSW in Shiraz City,Iran.The present study aims to evaluate the feasibility of using nano-MgO as a green low-carbon binder to remove MSW from the environment and make construction projects more cost-effective.Consolidated drained shear tests were conducted to evaluate the mechanical behaviors of the nano-MgO treated marl specimens at high normal stresses.The marl specimens containing MSW percentages of 15%,25%,35%,and 45%and nano-MgO percentages of 0.25%,0.5%,0.75%,and 1%,were used.It is found that the marl containing 15%and 25%MSW and 0.5%nano-MgO at 28-d curing can perform cation exchange and form new cementitious products.The soils with merely MSW show good performance due to the removal of the kaolinite and the formation of brucite.However,the soil with 25%MSW and 0.5%nano-MgO shows the same strength enhancement as the specimen with the optimal nano-MgO(0.75%)through the formation of dolomite,with a 20.59%increase in strain energy(SE).

Peri-urban Development:Discussion with Land Use Zoning,Statutory Provision,and Issues inside Katahari Rural Municipality,Nepal

The peri-urban area is a transitional zone between the city and its hinterlands characterized by mixed land use and intensive flows of resources,people,goods,and services from and to the city center.These zones are generally misguided and haphazardly developed without a proper planning framework.The peri-urban area at present will be the urban area in the future;therefore,it needs planning intervention in its initial stage of growth.Katahari,a peri-urban area of Biratnagar metropolitan city,is developing a spontaneous lack of land use plans.Recently,the Government of Nepal has encouraged the local government to implement land use plans in the provided framework,policy,and guidelines.This study,in this context,attempts to analyze and identify land use issues and potential zones for Katahari rural municipality that also supports planning urban development in the future.The study is based on primary and secondary data and information supported by maps and figures.It is concluded that Katahari has been developed as a multi-function center adjoining the Biratnagar metropolitan city,and future expansion of the city will cover a wide range of rural municipalities.The postal highway that passes through it has attracted a wide range of urban functions.Agriculture,residential,commercial,and industrial are the main land use category at present and needs development control through providing land use zoning and related planning instruments through the increasing role of the stakeholder and the government agencies in the decision-making processes and implementation of spatial development frameworks to regulate peri-urban development in the area which will guide the future planning for liability,economic viability,social inclusion,and environmental sustainability in the area.Spill-over development activities of Biratnagar,have increased the number of economic activities,population growth,and mixed-use development.

Global Research Progress on Municipal Waste and Future Prospect Based on the Cross-national Comparisons

Due to the acceleration of urbanization,the municipal waste(MW)problem has transformed into a global challenge for urb-an sustainability.To elucidate historical trends,current focal points,and future directions in MW research,we conducted a bibliometric analysis and employed knowledge graph visualization to scrutinize a total of 34212 articles,which were published between 1991 and 2021 in the Web of Science(WoS)core database.The results indicated that current major research themes encompass waste classifica-tion and recycling,waste management and public behavior,waste disposal methods and technologies,as well as environmental impact and evaluation.There has been a shift in the research focus from the environmental impacts of waste incineration to sustainable manage-ment related issues.A comparison of research from six typical countries revealed the differences in research priorities and techniques advantages.Scholars from the USA and Britain initiated MW research earlier than other countries and investigated management issues in depth,such as public behavior and willingness to pay.Meanwhile,Japanese,German,and Swedish scholars conducted extensive studies on advanced waste treatment technologies,such as disposal and recycling,risk assessment,and waste-to-energy techniques.Chinese scholars placed particular emphasis on end-of-pipe treatments and their associated environmental impacts.Hotspots and poten-tial future frontiers were identified by burst detection analysis.Keywords with high value of burst index(BI)worldwide are food waste and circular economy.Chinese scholars have put great efforts on waste environmental impact and its recycling technologies,while we’re expecting to further investigating vulnerable population.Furthermore,this study contributes to bridging the regional gap of scientific research among different countries and fostering international collaboration.

Selection of Water Transmission Method and Analysis of Pipe Network Zoning in Municipal Water Supply and Drainage Design

With the acceleration of urbanization,the demand for water supply and drainage pipe networks has increased significantly.In the planning of urban construction,it is necessary to optimize the design of the water supply and drainage system pipe network to effectively save energy while providing residents with more accessible water resources.Therefore,the municipal water supply and drainage system and the water transmission methods should be designed according to the geographical conditions of the city.In this paper,we mainly analyze the design of municipal water supply and drainage systems and the selection of water transmission methods.Besides,the optimization of the water supply and drainage network zoning process and pipe network maintenance is also discussed,so as to provide a reference for municipal water supply and drainage work.

Model Prediction and Optimal Control of Gas Oxygen Content for A Municipal Solid Waste Incineration Process

In the municipal solid waste incineration process,it is difficult to effectively control the gas oxygen content by setting the air flow according to artificial experience.To address this problem,this paper proposes an optimization control method of gas oxygen content based on model predictive control.First,a stochastic configuration network is utilized to establish a prediction model of gas oxygen content.Second,an improved differential evolution algorithm that is based on parameter adaptive and t-distribution strategy is employed to address the set value of air flow.Finally,model predictive control is combined with the event triggering strategy to reduce the amount of computation and the controller's frequent actions.The experimental results show that the optimization control method proposed in this paper obtains a smaller degree of fluctuation in the air flow set value,which can ensure the tracking control performance of the gas oxygen content while reducing the amount of calculation.

Physico-Chemical Quality of Selected Drinking Water Sources in Mbarara Municipality, Uganda

The study assessed the physico-chemical quality of selected drinking water sources (springs, boreholes, shallow wells and rainfall) in Mbarara municipality with respect to World Health Organization (WHO) drinking water guidelines and other guidelines in light of the increased anthropogenic activities in the municipality. A total of 70 water samples were collected from purposively selected boreholes, springs, wells and rainwater in Nyamitanga, Kamukuzi and Kakoba divisions of Mbarara municipality with various human activities. The samples were analysed for physico-chemical parameters: Temperature, pH, Dissolved Oxygen (DO), Biological Oxygen Demand (BOD), Total Dissolved Solids (TDS), Electrical Conductivity (EC) and Total hardness using American Public Health Association (APHA) standard methods. The mean temperature and pH ranged between 18.07 °C - 23.45 °C and 5.74 - 7.54, respectively. The mean DO values were found to be between 4.84 and 12.86 mg/l;whereas mean BOD was within the range of 1.83 - 7.71 mg/l. The mean TDS and EC of the water samples ranged, between 33.40 - 569.20 mg/l and 29.30 - 1139.90 μS/cm respectively. Furthermore, the lowest and highest mean total hardness were 70.00 and 264.00 mg/l, respectively. The recorded mean water temperatures for each of the water sources were above the WHO threshold temperature (15 °C) which makes drinking water palatable. Boreholes in Nyamitanga and Shuhaddea Secondary Schools, spring in Kiswahili, well in Kisenyi and rainwater in Mbarara University of Science and Technology (MUST) had mean pH below the WHO minimum guideline value (6.5) hence acidic. Borehole in Nyamitanga secondary school, spring in Kisenyi, shallow well in Nyamitanga and the rainwater in MUST had mean DO values below the WHO range (10 - 12 mg/l). Borehole in Shuhaddea Secondary School and the well in Kisenyi had average BOD values above the range of European Union guideline values (3 - 6 mg/l). TDS and EC of all the water sources were below the WHO maximum guideline limits of 1000 mg/l and 1500 μs/cm respectively. Total hardness was also below the WHO harmless limit of 1000 mg/l. However rainwater in MUST was moderately soft while the other drinking water sources exhibited moderate to full total hardness. The physicochemical parameters of some of the selected water sources in Mbarara municipality have been compromised mainly by the increased human activities especially croplands, latrines, landfills, transportation, animal and municipal wastes at the vicinity of the water sources. Mbarara municipal council should therefore ensure proper sanitation and water safety plans for these drinking water sources to avoid further contamination from the human activities.

The Physico-Chemical Quality of Effluents of Selected Sewage Treatment Plants Draining into River Rwizi, Mbarara Municipality, Uganda

As population increases in urban areas, the domestic and industrial activities increase resulting in an increase in the volumes of wastewater and anthropogenic pollution, hence posing a threat to public health and environment. This study assessed the physical chemical quality of two main sewage plant effluents discharging into River Rwizi. Effluent water samples were analyzed for dissolved oxygen, colour, turbidity, total suspended solid, total iron, phosphates, alkalinity, magnesium, calcium carbonate, temperature, pH, ammonium, electrical conductivity, chloride and nitrates. Parameters were analyzed following standard methods of APHA (1985). The values obtained were compared with EPA (2001), NWSC (2015) and NEMA (1999) standards for waste water. Results showed that the mean values most of the parameters tested were higher than the recommended EPA, NWSC and NEMA standards. The mean colour was 1627.67°C and 1414.33°C in Kakoba and Taso sewage effluents respectively compared to EPA (20-150), NWSC (500) and NEMA (300) standards (p > 0.05). The mean alkalinity was 1390.17 mg/l and 1308.33 mg/l for Kakoba and Taso respectively compared with EPA (400) and NWSC (800) standards. DO had a mean concentration of 68.27 mg/l and 63.03 mg/l in Taso and Kakoba respectively compared to EPA and NEMA standard of 5 mg/l. Mg was 243.29 mg/l and 246.49 mg/l in Kakoba and Taso sewage effluents respectively compared to NEMA standard for waste water of 100 mg/l (p > 0.05). The mean pH was 8.26 and 8.16 in Taso and Kakoba sewage effluents respectively compared to NWSC and NEMA standard of 6.0 - 8.0. Phosphate mean concentration levels were 32.2 mg/l and 27.11 mg/l for Taso and Kakoba respectively compared to standards of EPA (0.5 - 0.7 mg/l) and NEMA (10 mg/l). NO3 was 10 mg/l and 5.83 mg/l in Kakoba and Taso sewage effluents respectively compared to NWSC maximum permissible limit of 5 mg/l. The mean NH4 concentration was 385.33 mg/l (Kakoba) and 50.0 mg/l (Taso) compared to the EPA guideline range (0.2 - 4 mg/l). Chloride (Cl) had a mean of 833.33 mg/l in Kakoba compared to EPA (250 mg/l), NWSC and NEMA (500 mg/l) standards. Therefore the study recommends for effective treatment of waste effluents from Kakoba and Taso sewage treatment plants before recycling in order to avoid pollution of river Rwizi.

Availability, Range and Utilization of Sexual and Reproductive Health (SRH) Services for Adolescents at Kinondoni Municipality, Dar es Salaam—Tanzania

Background: It is estimated 1.2 billion of world’s population are adolescents aged 10 - 19 years;80% live in developing countries. Adolescents in developing countries especially Sub-Saharan Africa (SSA) face high burden of sexual and reproductive health problems. Sixteen million girls aged 15 to 19 years give birth every year of which 95% occur in low- and middle-income countries. Twenty five percent of unsafe abortions are in 15 - 19 years in Sub-Saharan Africa. Contraceptive use is low as approximately 10% of adolescents are current users. These problems can be averted if different ranges of Sexual and Reproductive Health Services for adolescent (SRHSA) are available and utilized by adolescents. In Tanzania, there is limited information addressing the availability, types and utilization pattern of sexual and reproductive health services by adolescents. This study investigates the availability, range and utilization of sexual and reproductive health services for adolescents (ASRHS) at Kinondoni Municipality, Tanzania. Method: A cross-sectional study was carried out in April to May 2013. A checklist was used to collect information on the availability and range of services offered at selected health facilities. In depth interviews conducted with in-charges of Reproductive and Child Health (RCH) clinics to explore barriers for provision of Sexual and Reproductive Health Services (SRHS) for adolescents. Adolescents were questioned using a questionnaire on utilization of SRHS and perceived barriers. Descriptive statistics were used to summarize quantitative data and content analysis for qualitative data. Results: On availability and range of adolescents’ sexual and reproductive health services, a total of 25 health facilities were surveyed. Forty four percent of the surveyed facilities did not have the adolescent sexual and reproductive health services (ASRHS). The Adolescents Sexual and Reproductive Health (ASRH) services offered differed greatly between facilities. On utilization of adolescents’ sexual and reproductive health services in total, 204 adolescents from the community were involved in this study. A third of adolescents reported to have ever used ASRH. The adolescents perceived barriers for underutilization of the services were fear of being seen at the clinics (23.3%), lack of money (18.3%), lack of privacy & confidentiality (14.2%) and unfriendly health care providers. Three barriers were perceived by health care providers in the provision of ASRHS: integration of SRHS, lack of training in relation to adolescents SRHS and attitudes of health care providers towards young people. Conclusion: About half of the health facilities did not have the SRH-services to adolescent (44%) and different ranges of services were not offered at the facilities as it was shown in the records. The results from this study show services were underutilized by adolescents. Training, attitudes of health care providers towards young people, & cost influenced ASRHS provision and utilization. Strategies to increase training in ASRHS for health providers including communication skills and scaling ASRH services to all primary care facilities may help to improve availability and access of services to adolescents.

Effect of a Malaria Control Program on the Prevalence of Malaria, Fever and Anaemia in Children under Five Years in the Hohoe Municipality of Ghana: A Comparative Analysis of Cross-Sectional Surveys

Background: Malaria and anaemia continue to adversely impact the health of children in Ghana. Hohoe is an area of intense and prolonged, seasonal malaria transmission. In 2006, malaria control programme activities which provided In-secticide Treated Bed-Nets (ITNs) to resident children under five years and Artemisinin Combination Therapies (ACTs) for the management of malaria were introduced into the Hohoe Municipality. Before the introduction of the control programme, baseline surveys were carried out in communities in the Hohoe municipality to determine the prevalence of malaria, fever, anaemia, malaria parasite density, gametocytaemia and ITN ownership and use in June and November 2006 ahead of the intervention programme. Similar surveys were conducted in 2010 after the intervention to assess changes in the earlier indicators in the same communities. This report presents an evaluation of the intervention by comparing findings before and after the malaria control interventions. Methods: In 2010, two community-based surveys were carried out in thirty communities among children aged five years and below. The first one was at the beginning of the rainy and high malaria transmission season in June and the other was in November at the end of the rainy season. The surveys were to determine the prevalence of malaria, fever, anaemia and ITN ownership, use and effectiveness among children less than 5 years. Data were collected in the form of interviews using questionnaire and collection of biological samples. Findings were compared to those similar surveys conducted in the same communities and age groups in 2006. Pr-testi was used to analyze two sample tests for proportions and t-test was used for means. Findings: Malaria prevalence decreased by 20% [9.0% vs. 7.2%;p = 0.0.40], fever decreased by 47.8% [2.3% vs. 1.2%;p = 0.008] and anaemia decreased by 32.9% [7.8% vs. 5.3%;p = 0.002]. ITN ownership increased by 67.9% [20.8% vs. 64.8%;p < 0.001], ITN use increased by 64.2% [15.1% vs. 42.2%;p < 0.001] and ITN effectiveness increased by 41.7% [20.0% vs. 34.3%;p < 0.001]. The proportion of children with high density parasitaemia reduced by 17.9% [2.8% vs. 2.3%;p = 0.223]. Gameto-cytaemia decreased by 82.5% [0.8% vs. 0.14%;p = 0.002. Similarly data comparing 2006 and 2010 post-rainy season showed that malaria prevalence decreased by 16.8% [40.4% vs. 33.6%;p < 0.001], fever decreased by 14% [5.0% vs. 4.3%;p = 0.347] and anaemia decreased by 64.2% [12% vs. 4.3%;p < 0.001]. The proportion of children with high density parasitaemia also reduced by 69.5% [10.5% vs. 3.2%;p < 0.001] and gametocytaemia decreased by 78.5% [0.8% vs. 0.17%;p = 0.008]. Conclusion: This study suggested that there was an association between the current intervention and reduction in the prevalence of malaria, fever and anaemia. High parasite density and gametocytaemia prevalence have also significantly reduced over the five years of the introduction of the control measures. There has also been a significant increase in the ownership and use of ITNs.

Maintenance of Municipality Infrastructure: A Case Study on Service Delivery in Limpopo Province at South Africa

Purpose: An element of poor service delivery concerns the quality of management on the maintenance of services like water, electricity, roads, schools and clinics. This is a relevant and topical issue for research because of the current situation regarding these provisions in South Africa. This research took place in a Municipality situated in Limpopo Province, South Africa. It is the responsibility of municipalities to ensure that they fulfil their constitutional obligations in the delivery of maintainable, operative and well-organised municipal services through the maintenance of infrastructure. As this country has been subjected to a large number of service delivery complaints, this has led to the motivation of this study. The purpose of this study is to analyse maintenance on municipal infrastructure and service delivery in a local municipality, in particular focusing on the water supply. This research study is aimed at analysing how local municipality conducts its maintenance of municipal infrastructure, seeking to understand the challenge of maintenance on service provided to the communities. Design/Methodology/Approach: To achieve the success of this research, both qualitative and quantitative methods were adopted. A survey questionnaire and structured interview questions were conducted with communities and employees in a municipality in Limpopo Province. Findings: The results of the study revealed that residents are facing water difficulties due to a lack of maintenance and absence of water supply. People are fetching water from the rivers in the nearby community, water which unfortunately is not purified. Furthermore, people have experienced this poor maintenance and service delivery for years, negatively impacting on the community’s standard of living. Originality/Value: The original contribution of this work was to analyse the types of maintenance being used in local municipalities and how it will benefit the communities. To the best of the authors’ understanding, there are no studies that have been conducted in South Africa regarding the impact of maintenance on municipal infrastructure, and this paper aims to fill this gap.

Bacterial Analysis of Selected Drinking Water Sources in Mbarara Municipality, Uganda

Surveillance of water quality to ensure microbiological safety is a vital public health function to prevent water borne diseases. Bacterial total coliform and Escherichia coli (E. coli) examination provide indication of the hygienic condition of drinking water and are major tools in the assessment of the health risk borne by pathogen in water. Unfortunately, there is insufficient information on the total coliform and E. coli amounts in the common drinking water sources in Mbarara Municipality, Uganda despite the eminent anthropogenic sources of contamination. Hence the study established the sanitary risk and quantified the total coliform and E. coli load in selected drinking water sources in Mbarara Municipality, Uganda. A total of 70 water samples were collected from selected boreholes, springs, wells and rainwater in Nyamitanga, Kamukuzi and Kakoba divisions of Mbarara municipality. The water samples were analysed for total coliform and E. coli abundance using the American Public Health Association (APHA) standard method. The total coliform and Escherichia coli counts were compared with the World Health Organization (WHO) drinking water standard guidelines. The findings indicate that all the studied groundwater sources (boreholes, springs and wells) in Mbarara Municipality were not compliant to either both or one of the WHO total coliform ( ml) and E. coli (0 CFU/100 ml) criteria for drinking water hence they are unsuitable for drinking without treatment e.g. boiling etc. Only rainwater collected from Mbarara University of Science and Technology met the WHO total coliform and E. coli criteria for drinking water thus is suitable for drinking without any treatment. There is a strong linkage between bacterial (total coliforms and E. coli) water quality and water source sanitation, as well as the proximity of latrines, animal farms and landfills around the water sources. Mbarara municipal council should therefore ensure effective and regular operation and maintenance of the drinking water sources through the adoption and promotion of appropriate water safety plans.

Suitability of Drinking Water Sources from Nyaruzinga Wetland for Domestic Use in Bushenyi Municipality, Uganda

This study determined the physico-chemical and bacterial quality of raw (bore-hole, springs, wells) and tap water sources from Nyaruzinga wetland for domestic use in Bushenyi Municipality. Forty samples of raw water were randomly collected from Kacuncu, Kyeitembe and Kikuba tributaries of the wetland and 40 samples of tap water generated from the same wetland were randomly drawn from Ishaka, Nyakabirizi and Central divisions of the Municipality. The samples were analyzed for apparent colour (AC), turbidity, electrical conductivity (EC), total hardness, pH, total iron, residual alum, free residual chlorine and faecal coliforms using standard methods and their values compared with standard local UNBS (2008) and international WHO (2011) drinking water quality guidelines. The results showed that the mean pH of the protected spring below Kikuba Hill (5.21);the AC (Pt/Co) of the borehole below Bweranyangi Junior School (17.28) and the surface well below Nyandozo Primary School (157.58) both situated in Kacuncu as well as the free residual chlorine (mg/L) in tap water at Kanyamabona Trading Centre, Ishaka division (0.192) were below the standard values of WHO (pH, 6.0 - 8.0;free residual chlorine, 0.2 - 0.5) and UNBS (AC, <15). The electrical conductivity, EC (μS/cm) and total hardness (mg/L) of all the selected water sources were within the WHO standards (EC, <1500 (raw water), 0 - 300 (tap water);total hardness, <1500 (raw water), <100 (tap water)). The residual alum (mg/L) in all the tap water sources was also within the WHO guideline (<0.2). On the other hand, the turbidity (27.38 NTUs) and total iron content (0.32 mg/L) of the surface well below Nyandozo Primary School were above WHO guidelines of <15 and <0.3 respectively. Furthermore, the mean faecal coliform counts (CFU/100 ml) in the surface well below Nyandozo Primary School (6.90) and the borehole below Bweranyangi Junior School (16.83) including the surface well below Kyeitembe Trading Centre (9.25) were above the WHO standard faecal coliform count (≤3 TCUs). Only the tap water at Kanyamabona Trading Centre recorded mean faecal coliform counts (0.25 TCUs) beyond the WHO standard (0 TCU). Hence the quality of tap water within the municipality tapped from Nyaruzinga wetland was generally better than the raw drinking water sources (borehole, springs, wells) from the same wetland. Thus the use of piped tap water by the urban inhabitants as opposed to raw water sources needs to be promoted to increase access to safe water.

Prevalence, Knowledge and Associated Determinants of Auto-Medication in the Limbe Municipality

Introduction: The practice of auto-medication is on the rise in most sub-Saharan countries. The effects of these may be associated with increased drug resistance in the future, complication of the course of a disease, adverse drug interactions etc. Auto-medication is of course a global public health concern, which requires appropriate attention to evade future undesirable effects. Aim: The aim of this study was to investigate the knowledge, prevalence and associated determinants of auto-medication in the Limbe municipality. Method: This was a community-based cross-sectional study, conducted among 284 enrolled participants in Limbe Health District between January to August 2021. A structured questionnaire-based interview was used to collect data from each study subject. Then, data were categorised and analysed using SPSS version 20 software. Results: Majority of 213 (75%) of the participants practised auto-medication. The most frequently reported auto-medication symptoms were fever and headache 202 (71.1%). 95 (15.6%) practised auto-medication because they believed it saved time, meanwhile 5 (0.8%) had the belief that health personnel are too busy in the hospital with lots of patients to serve. Concerning knowledge, 68.9%, 13.1% and 18.2% had grading as Good, Poor and uncertain respectively. 58.3% of participants had a positive attitude towards auto-medication while 12.7% were indifferent. Factors associated with the use of auto-medication included: Age (p Conclusion: The prevalence of auto-medication remains increasingly high;there is a need for community sensitization to avert the negatives of such practices. The knowledge on auto-medication is fairly above average.
